Pedal Monsters is a small custom guitar effects pedal builder based in Rockville, Maryland, with pedals handmade in the Washington, D.C. area. The shop is best known for its Klone overdrive, a take on the Klon Centaur circuit that put the brand on the map and has been offered in standard, Gold, and Klon Klone Jr. variations.

Beyond the Klone, the lineup includes a Custom TS808 Clone (a Tube Screamer-style overdrive), the Heisenberg Dual Drive, the White Lightning V2, and the Bright Lights Overdrive. The builder also takes on commissioned custom clone work, collaborating with players on cosmetics and tonal targets, and sells branded merchandise alongside the pedals.

Positioned in the affordable end of the boutique market, Pedal Monsters emphasizes handmade construction at accessible price points rather than chasing high-end finishes or proprietary circuits. The brand is sold direct through its website and has a presence on Reverb and through select small dealers.

Pedal Monsters has 3 products cataloged on Equipboard, including Overdrive Effects Pedals and Boost Effects Pedals.
